Has anybody tried these strings? I want to experiment with a different type of flatwound, but don't want to waste a lot of money if I don't like the feel. I am currently running LaBella Low Tension flats that came on my fretless Spector. Nice sound, but the B string is really tubby, almost to the point of being unusable. I mostly use this bass for Jazz or Rockabilly stuff. I cannot use coated strings because of the Fishman system on the bridge pickup.
